FILM-RECEPTACLE AND SUPPORT THEREFOR.

Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed March 11, 1915. Serial No. 13,814.

To all whom t may concern.'

Be it known that I, @nannies` UEBELMESSER, a subject of the Emperor ofGermany, resid ing at New York city, in the county and State of NewYork, have invented certain new and useful Improvements in ImprovedFilm-Receptacles and Supports Therefor, of which the following is aclear, full, and eX- act description.

This invention relates to an improvement in motion picture devices butrelates more particularly to the lm receptacle and support therefor.

One object of this invention is to provide a reel receptacle arranged toretain a reel of film and also to permit the reel to be unwound, andrewound within the same box or receptacle, the said film being caused topass adjacent to a lens exteriorly of the receptacle therefor. By meansof my improvement a large amount of space is saved, an eXtra film reelreceptacle being obviated, consequently the size of the motion pictureapparatus can be greatly reduced in size.

In the drawings which form part of this specification- Figure 1 is asectional view illustrating diagrammatically the mechanism for oper`ating a film and also my improved means for supporting a film reel.

Fig. 2 is a sectional plan view thereof, the section being taken on aline 2 2 in Fig. 1.

Fig. 3 is an enlarged perspective View of a portion of my improvement.

u Fig. 4 is an enlarged sectional detail view of the lower portion ofthe rewinding arm.

As herein illustrated my improvement consists of a receptacle 1 forcontaining reel of film 2 which is operated by suitable sprockets 3, 4,5 and 6 and a film advancing hook 7 of any well known type. The hook 7is operated to advance the film 3 by intermeshing gears 8 and 9, saidgears being rotated by a gear 10 meshing with the gear 8.

The gear 8 is pivoted to the hook at 11 and is therefore reciprocatedvertically when the gear 8 is rotated. The gear 9 carries a pinV 12engaging a slot 13 in said hook 7. The rotation of the gear 9 causes thehook to reciprocate whereby the end 14 is caused to engage the openings15 in the film 3 at the end of the upward stroke of the hook 7 and toleave the openings at the lower end of the stroke of the hook 7. Thislform of film advancing device is well known.

To operate the gears 8, 9 and 10 I mount upon the shaft 16, of the gear10, an operating handle 17. The shaft 16 also carries a gear 18 whichdrives a gear 19 which in turn operates four sprockets, two only, 19*Land 19", being shown in Fig. 2, all of which are carried by a shaft 20.The sprocket gears on theshaft 20 operate other sprockets 21 and 22 on ashaft 23 which operate a sprocketl 24 on the shaft 25 for the filmsprocket 4, the film sprocket 3 being carried by the shaft 23. The lowerfilm sprockets 5 and 6 are carried by shafts 26 and 27 respectively,said shaft being operated from the shaft 20 by a system of sprocketgears and chains. The above mentioned mechanism is merely an arbitraryform of film operating mechanism and is in no way essential to myinvention.

This invention comprises a film supporting mechanism consisting of anarm 27 a pivoted at 28 to the receptacle 1, an arm 29 also pivoted tothe receptacle 1 at 30, a link 31 connecting said arms, and means towind the film. The above mechanism is one way of carrying out myinvention. Other means might be employed without departing from thespirit of the invention. For the sake of clear-ness I will term the arm27 L the carrier arm and the arm 29 the rewinding arm, although botharms carry the film.

To carry out'my invention I preferably.

employ a film band such as 3 wound upon a spool 31, which can be slippedonto the carrier spindle 32, said spool not having any flanges.

The rewinding arm 29 is provided with a rotatable spindle 33, Fig. 4driven by a sprocket 34, in this instance. The spindle 33 is threadedinto a shaft 35 driven by the sprocket 34. The shaft 35 travels in aslot 36 in the casing 1 in this instance.

The gear 34 is operated by a chain 37 passing around a sprocket gear 38loosely mounted on the pivot-pin 30 for the arm 29. The gear 38 issecured at 30a to a sprocket gear 39 also loose upon the pin 30. Tofacilitate the securement of the film to the spindle 33 I provide thesaid spindle with a tab 40 of any fieXilole material thin enough to bewound upon the spindle 33. From the material of the tab I strike outfingers 41 arranged to engage the openings 15 in the film 3.

To thread the film 3 I open the door 42 of the casing l, that is when Iload the device, and pass the tab l() through the opening 43 in thecasing l. I then place the reel 31 upon the spindle and thread the endthereof through the opening 44k in the casing thence around the varioussprockets. I finally cause the fingers on the tab Ll0 to engage the endopenings 15 in the film and operate the machine enough to wind a fewfeet of film upon the spindle 33. As this device is more especiallyintended for motion picture cameras the above operation will beperformed in a dark-room.

IVhile the device is operating, to photograph a scene, for instance, theamount of film upon the spindle 33 will increase and the amount upon thespindle 3l will decrease until the entire film is taken from the spool.3l and wound upon the spindle 33.

As the roll of film upon the spindle 33 increases in size it willgradually swing the arm 29 to the left due to its contact with the guiderollers 45 and d6.

As the arm 29 swings to the left the arm 27 will also swing to the leftdue to the provision of the connecting link 3l. A s the roll of fihnupon the spindle 33 increases it will be moved toward the center of thecasing l, in this instance, and the decreasing roll upon the spindle 3lwill move toward the upper corner 17, and when the film is entirely usedup it will have been wound upon the spindle 33 and the arms 27a and 29will be reversed in position. By this means I ain able to utilize asingle receptacle within which a film can be placed, unwound, andrewound upon another carrier.

The apparatus can now be carried to a dark room and the film taken out.To remove the filn., I remove the spindle from the sprocket 34 and slideit out of the arm 29. I may place another spindle such as 33 in positionor' wait until the film is developed and use the same spindle that wasremoved. TWhen the film is unwound from the spindle the tab 40 canbeleasily removed. The gear 34C is connected to the spindle 33 by afriction clutch mechanism l-S to keep said spindle from ruiming ahead ofthe other sprockets when the roll thereupon reaches a relatively largediameter.

As has been stated, the film advancing mechanism is merely diagrannnaticto illustrate a motion picture camera.

IVhat I claim is:

l. In a motion picture device a receptacle to contain a film, a movablecarrier therefor, means to feed said film from said receptacle, aseparate rewinding movable carrier within said receptacle and means torewind said film upon said rewinding movable carrier.

2. In a motion picture device a receptacle to contain a film, a movablecarrier therefor, means to feed said film fronl said receptacle, aseparate movable carrier within said receptacle, means to rewind saidfilm upon said rewinding -movable carrier, and means connecting saidcarriers.

3. In combination with a motion picture device, a Vfilm receptacle, amovable carrier for said film, means to feed said film while on saidcarrier, an independent movable carrier to receive said film as it isfed from the carrier first named, and means to move said carrierssimultaneously in the same direc tion.

In a motion picture device a film reccp tacle, ,ar carrierI for saidfilm consisting of a pivoted arm within said receptacle, means to feedsaid film from said carrier, a second pivoted arm carrier within saidreceptacle, a rotatable spindle carried thereby to rewind said film,means to rotate said spindle, and means to cause said arms to move inthe same direction while said film is being rewound.

In a motion picture device, a -film receptacle, a movable carrier forsaid film, a second, movable carrier within said receptacle, meansconnecting said carriers, means carried by the second carrier to receiveand rewind said film, and means to move said carriers sinmltaneously asthe diameter of the rewindingl film increases.
